Specification of Letters Patent.

Patented June 3, 1919.

Application filed September 5, 1918. Serial No. 252,702.

To all whom it may concern:

Be it known that I, EVERETT T. PACKARD, a citizen of the United States, residing at Avon, in the county of Sufi'olk, in the State of Massachusetts, have invented a certain new and useful Improvement in Lug-Straps, of which the following is a specification, reference being had to the accompanying drawlngs.

This invention relates to lug straps for' 4 is a horizontal, sectional, view taken at the point 4-4 of said Fig. 3. Fig. 5 is a detached, top view of a slightly'modified construction of the lug strap, and Fig. 6 is a horizontal, sectional view taken on the line 6-6 of Fig. 7; said Fig. 7 being a side elevation of said lug strap.

Referring now to these drawings, the letter (4 indicates a portion of a picker stick of the usual, or any other approved, construction and 1) denotes the customary sweep stick to which the lug strap is secured by means of bolts 0-0.

The lug strap, as here shown includes an outer strap d of sheet metal which is cloubled upon itself to provide a curved end portion d, in which is seated a buffer block 6, also plates f-f formed preferably of wood, which are located, in opposition to each other, on the inner faces of the strap cl; the said plates being of such length that their inner ends abut the buffer '6 and thusprevent said buffer from working forward; that is to say, away from its seat in the curved end portion d of the metal strap. The buffer 6 is formed preferably of a composition which consists in part of rubber andwhich is slightly resilient so as to cushion to some extent the rigid shock which would otherwise result. from the impact of the picker stick with said buffer.

By preference the inner face of the buffer is formed at its mid portion with a curved or rounded face 6 where it engages the picker stick and at theopposite sides of said curved portion the buffer may be cut away vertically, as at e Fig. 6, to receive the squared ends of the side plates ff. In the buffer shown in Figs. 1, 2, 3 and 4 the curved portion of the buffer extends from. sideto side of the buffer and the engaging ends of the said plates ff are correspondingly curved to. fit the same. By preference the wooden side-plates f'f are riveted to the metal strap 03 as is best seen at gg inFigs. 4 and 6.

In order tosupport the lug strap in the proper position with respect to the picker stick, I may provide in the bufi'er an eyebolt h which is adapted to receive a strap 2' whose upper end is fastened to the picker stick in the usual manner and, forthe purpose of preventing the accidental disan rangement of the bufi'er e, I pass a cotter pin 70 through said buffer and through the metal strap'd, in the form of lug strap shown in Figs. 5, 6' and 7 but in the construction illustrated in Figs. 1, 2, 3 and 4the cotter pin is not necessary, as the curved ends of the side plates ff serve to prevent such disarrangement.

I find by continued practical use that the composition buffer 6 will wear satisfactorily for a much longer period of time than the leather or raw-hide bufi'ers now commonly used. When, however, it becomes necessary to remove a worn-out louder and replace it with a new one, it may be readily done in the strap of Figs. 5, 6 and 7 by removing the cotter pin 70 and sliding the buffer upward, or downward, until it leaves the strap cl whereas in the structure of Figs. 1, 2, 3

and 4 it is necessary to remove thestrap from the sweep stick and spring the'sides of said strap apart in order to remove the worn buffer and to replace it with a new one.

Having thus" described my invention, I

an outlining strap doubled upon itself, a buffer seated in the doubled end portion of said strap and opposing plates located in said strap; theends of said plates abutting the buffer.

2. The improved picker stick consisting of an outlining sheet metal strap doubled upon itself, a resilient buffer seated in the doubled end portion of said strap, opposing plates located in said strap and abutting the said 10 buffer, and means for preventing the vertioa-l movement of the buffer in said strap.
